Background information

Chamber creation

The Chamber of Secrets was a enormous chamber built by the Founder of Hogwarts and Slytherin House, Salazar Slytherin in the 11th century. The chamber leads from the Second-floor girls' lavatory down through a chute to a circular room. That room has a hole that leads into a large room that has a door at the end of it. One has to speak Parseltongue to open it. The door leads into the main chamber, which is a very large room with a little swimming-pool at the end and a wall-statue of Slytherin himself. The mouth is used to hide an enormous Basilisk, which only emerges when the Heir speaks to it via Parseltongue. On the long way to the end some snake-head statues are to be found. There is also a passage on the right which leads into a walk, with another long walk and a short walk. They both leads to the main chamber. However, in 1992, the circular room had a lot of rat-bones, and the large room with the door at the end was crushed, when Gilderoy Lockhart used Ronald Weasley's wand to perform the Memory Charm which backfired, and caused a lot of rocks to block the way, and the same room had a Basilisk-skin which had been shed.

Second Stage

Before the next school year, Death EaterLucius Malfoy distracted the Weasleys while they were shopping at Flourish and Blotts, and slipped Tom Riddle's HorcruxDiary in the seventhWeasley's cauldron. After the first couple of months, the memory of Tom Riddle took over Ginny, and forced her to petrify several students. Finally, Harry Potter found the diary, but Ginny stole it back from him and then, she finally went down into the Chamber of Secrets, where Tom Riddle's memory came out of the diary and took human form. Harry traveled down to the Chamber and learned Riddle was Voldemort.

"So this is what Dumbledore sends his great defender, a songbird and an old hat... Speak to me, Slytherin, greatest of the Hogwarts Four... Let's match the power of Lord Voldemort, Heir of Salazar Slytherin against the famous Harry Potter... Kill him"

Riddle then summoned the basilisk, while draining Ginny's life from her. Riddle made it clear that his new goal was to kill Harry Potter instead of the Muggle-born students, since Ginny had revealed to him that Harry was meant to kill him in his future. There was then a battle and the basilisk was killed. Riddle tried to stop a dying Harry Potter from destroying his diary, but failed again.

Aftermath

After the battle Harry Potter, with Dobby's tacit hints, was able to correctly surmise Lucius Malfoy's involvement in the opening in the Chamber of Secrets, with Albus Dumbledore concluding that Lucius slipped the diary to Ginny Weasley for personal gain, in hope of sabotaging the Muggle Protection Act her father, Arthur Weasley, had recently proposed in the Ministry of Magic. As the diary lost its magic upon its destruction, there was not sufficient proof for these allegations, though Lucius did lose his position as a Hogwarts school governor for threatening his fellow 11 colleagues, as he had used the incident in an attempt to remove Albus Dumbledore from Hogwarts.
